ORCAS Picarro Data

Summary

This dataset contains atmospheric measurements of carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), and water vapor (H2O) mixing ratios made with the NOAA Picarro Cavity Ring Down Spectrometer (Crosson 2008) instrument onboard the NSF/NCAR GV HIAPER (Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research) aircraft (Tail Number N677F) during the ORCAS (O2/N2 Ratio and CO2 Airborne Southern Ocean Study) campaign with research flights from Punta Arenas, Chile from 7 January to 1 March 2016.
